Problems solved by technology

This method of wetting has the disadvantage that the amount of wetting agent can be very imprecise due to the application of the wetting agent under steam conditions
Furthermore, the application of steam is always accompanied by a relatively high loss of wetting agent

Abstract

The invention relates to the technical field of chemical products, in particular to an anticorrosive architectural coating. The anticorrosive architectural coating is prepared from the following components in parts by weight: 25 to 30 parts of methyl vinyl silicone rubber, 1 to 2 parts of a dispersing agent, 3 to 4 parts of water absorbing resin, 45 to 60 parts of fluororesin, 40 to 45 parts of toluene isocyanate, 8 to 10 parts of polyurethane and 15 to 25 parts of aromatic hydrocarbon. The anticorrosive architectural coating disclosed by the invention has strong weathering and alkali resistance, can adapt to different climate changes, is environmentally friendly and energy-saving, and does not cause harm to the environment and a human body. The anticorrosive coating used has a good formulation effect and can be widely used in the fields of engineering construction, mechanical assembling and the like to meet the diversified demands of the market.

Description

technical field [0001] The invention relates to the technical field of chemicals, in particular to an anti-corrosion architectural coating. Background technique [0002] In pressing methods for the production of slabs of material, it is known to moisten the mass of material during or immediately before pressing, thereby infiltrating the material by steam explosion and thus transferring heat to the mass to Accelerates the setting of the binder within the block of material. For example, from EP1508414A2 it is known to apply steam to one side of a block of material in a press, wherein an attempt is made to introduce as little steam as possible in order to prevent the binder from being washed out and to be able to shorten the pressing process as much as possible. It is known from DE 10 2006 058 612 A1 to moisten the mass of material with steam before pressing. This method of wetting has the disadvantage that the amount of wetting agent can be very imprecise due to the applicat...
